"err" is not initialized when failing to create and add the freq0 sysfs
file. Remove it from the message. This fixes the following warning with
clang:
	../drivers/gpu/drm/xe/xe_gt_freq.c:202:30: error: variable 'err' is uninitialized when used here [-Werror,-Wuninitialized]
				 kobject_name(gt->sysfs), err);
							  ^~~
